Assessing the Aged Prestress Concrete Girder’s Quality in Al-Rayhanna Bridge Using NDT

Journal of Engineering
Many of the Iraqi highway bridges (especially in Anbar Province) are in poor condition even after they have been checked and determined to satisfy acceptable standards due to the effect of many risk factors. These risks are related to factors such as the

Prediction of Concrete Compressive Strength Based on Gradient-Boosting ABC Algorithm and Point Density Correction

Eng
Accurate prediction of concrete compressive strength is essential for ensuring structural safety in civil engineering, particularly in road and bridge construction, where inadequate strength can lead to deformation, cracking, or collapse. Traditional non-
